Please add the ability to bond multiple Gig Ethernet interfaces to increase transfer speed -- nearly quadruple it!
While this feature should be avoided by beginners, advanced users who use your device as an archive target for very large backups will definitely appreciate it. I should think it would be a significant product differentiator in the NAS market.
The N5200B and N5200BPro has this feature in it already. The N5200BR and N5200BRPro does not.
Link Aggregation is included and just needs to be turned on. Now, you do have to have a network switch that supports it also. According to Thecus, all hardware must support IEEE 802.3ad and then it will work. I have not tried it myself, as I have the N5200BR variant.
Normally, IP Sharing is something totally different, so unless Thecus uses the name incorrectly, that would not be it. I'm not near mine, so I can't check right now. I know that on the N5200BR, the option for Link Aggregation is not available and not on the menu.
On a side note, in terms of creating a module to allow this on the BR machines, I am not sure if it is possible or not. Both machines are exactly the same, with the exception of one has a switch/hub installed and one had a secondary NIC installed onto the same point on the motherboard. The switch/hub and secondary NIC is an interchangeable daughter card, and upon boot, the OS checks for the existence of the Switch, if it exist, then it disables the Link Aggregation option. I have not looked to see if the Switch is just a HUB, or if it is an addressable Switch which would allow using VLANs. If the switch does allow VLANs, then it would be possible to create a module to add this feature to the BR systems also.
I've had a good experience using the Thecus N7700 with two ethernet ports bound to two high-speed L2 switches.
One network was connected to the first switch while the second network was connected to the second switch. Both switches were connected internally with a gigabit link.
The speeds and throughputs were astonishing. This was in use in a data center for several years. The Thecus 2000 were already having this feature, been connecting those double ports years ago as fail-over and aggregration link before the N7700 got in use.
